As the cost of storage falls and USB transfer speeds improve, USB memory sticks are cheaper, faster and more capacious than ever before. For prices starting at just a few dollars, you can keep copies of all the personal files on your PC right in your pocket.

There are also different physical plugs types. Most USB sticks still use the original USB-A plug with the rectangular profile, but some use the rounded USB-C plugs instead, and a few even use Apple's Lightning plug as an option.
Different USB sticks also have different read and write speeds. For transfers of large files, you'll definitely want something fast. Some drives also offer built-in encryption should the drive get lost or fall into the wrong hands.

How to choose the best USB drive for you
When buying USB flash drives, you'll want to focus first on storage. If you have a large number of files, videos, or songs you want to carry around with you on a device, getting a USB drive with at least 64GB is critical, and many go up to 256GB or more.
If you're more concerned about getting a cheap memory stick for carrying fewer files, you can probably get by with 16GB or 32B.
Aside from that, you’ll want to consider other critical features, like read/write speeds. The faster the speeds, the more data you can write to the drive and access when you’re trying to see files. That’s why we would look for USB 3.1 support or (at the least) USB 3.0 support if you care about performance.
Another factor to consider is design. Flash drives aren’t the sexiest of devices, but they come in a variety of shapes and sizes. In terms of durability, look for USB drives that have shock-proof designs, waterproof-designs, and other features that limit chances of your drive being damaged. Last but least, check the warranty on that USB flash drive; a lifetime warranty is preferred but 5 years is a decent fallback option.
